• FastDFS高可用集群架构配置搭建


    https://www.cnblogs.com/sunnydou/p/49b92d511047f4f9da6cd727cfd415d5.html(文章出处)

    一、基本模块及高可用架构

    FastDFS 是余庆老师开发的一个开源的高性能分布式文件系统(DFS)。 它的主要功能包括:文件存储,文件同步和文件访问,以及高容量和负载平衡。
    FastDFS 系统有三个角色:跟踪服务器(Tracker Server)、存储服务器(Storage Server)和客户端(Client)。

    • Tracker Server: 跟踪服务器,主要做调度工作,起到均衡的作用;负责管理所有的storage server和group,每个storage在启动后会连接 Tracker,告知自己所属 group 等信息,并保持周期性心跳。多个Tracker之间是对等关系,不存在单点故障。
    • Storage Server: 存储服务器,主要提供容量和备份服务;以 group 为单位,每个 group 内可以有多台 storage server,组内的storage server上的数据互为备份。
    • Client:客户端,上传下载数据的服务器
      模块之间的主要关系如下:

    下图是实现统一的对外下载访问入口的高可用架构,其中所有的Nginx只做下载用途,上传通过tracker进行上传。

    二、环境准备工作

    系统软件说明:

    名称 说明
    CentOS 7.x(安装系统)
    libfastcommon FastDFS分离出的一些公用函数包
    FastDFS FastDFS本体
    fastdfs-nginx-module FastDFS和nginx的关联模块,解决组内同步延迟问题
    nginx nginx 1.12.2(CentOS 7 下YUM可以安装的最新版本)

    整个搭建所需环境资源及用途如下表:

    名称 IP地址 应用
    tracker01 192.168.0.1 FastDFS,libfastcommon
    tracker02 192.168.0.2 FastDFS,libfastcommon
    storage01 192.168.0.10 FastDFS,libfastcommon,nginx,fastdfs-nginx-module
    storage02 192.168.0.11 FastDFS,libfastcommon,nginx,fastdfs-nginx-module
    nginx01 192.168.0.100 nginx,keepalived
    nginx02 192.168.0.101 nginx,keepalived
    VIP 192.168.0.200 -

    三、安装过程

    1、编译环境准备

    说明 位置
    所有安装包 /opt/fastdfs
    数据存储位置 /data/fastdfs
     
    $ tar -zxvf libfastcommon-1.0.39.tar.gz
    #安装编译环境
    $ yum groups install Development Tools -y
    $ yum install perl -y
    $ mkdir -p /opt/fastdfs /data/fastdfs
    $ cd /opt/fastdfs  #为下一步下载源码做准备

    2、安装libfastcommon

    #下载文件
    $ wget https://github.com/happyfish100/libfastcommon/archive/V1.0.39.tar.gz
    $ tar -zxvf libfastcommon-1.0.39.tar.gz
    $ cd libfastcommon-1.0.39/
    $ ./make.sh
    $ ./make.sh install

    3、安装FastDFS

    复制代码
    $ wget https://github.com/happyfish100/fastdfs/archive/V5.11.tar.gz
    $ tar -zxvf fastdfs-5.11.tar.gz
    $ cd fastdfs-5.11/
    $ ./make.sh
    $ ./make.sh install
    #配置文件准备
    $ cp /etc/fdfs/tracker.conf.sample /etc/fdfs/tracker.conf #tracker节点
    $ cp /etc/fdfs/storage.conf.sample /etc/fdfs/storage.conf #storage节点
    $ cp /etc/fdfs/client.conf.sample /etc/fdfs/client.conf #客户端文件,测试用
    $ cp /opt/fastdfs/fastdfs-5.11/conf/http.conf /etc/fdfs/ #供nginx访问使用
    $ cp /opt/fastdfs/fastdfs-5.11/conf/mime.types /etc/fdfs/ #供nginx访问使用
    复制代码

    tracker server配置:

    复制代码
    $ vim /etc/fdfs/tracker.conf
    #需要修改的内容如下
    port=22122 # tracker服务器端口(默认22122,一般不修改)
    base_path=/data/fastdfs # 存储日志和数据的根目录
    #编辑启动文件
    $ vim /usr/lib/systemd/system/fastdfs-tracker.service
    [Unit]
    Description=The FastDFS File server
    After=network.target remote-fs.target nss-lookup.target
    
    [Service]
    Type=forking
    ExecStart=/usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf start
    ExecStop=/usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf stop
    ExecRestart=/usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf restart
    
    [Install]
    WantedBy=multi-user.target
    
    $ systemctl daemon-reload
    $ systemctl enable fastdfs-tracker.service
    $ systemctl start fastdfs-tracker.service
    $ netstat -tulnp #查看服务是否启动,端口是否打开

    如果没有打开需要手动打开

    (5)手动启动tracker,运行如下命令:

    /usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf restart
    复制代码

    storage server配置

    复制代码
    $ vim /etc/fdfs/storage.conf
    #需要修改的内容如下
    port=23000 # storage服务端口(默认23000,一般不修改)
    base_path=/data/fastdfs # 数据和日志文件存储根目录
    store_path0=/data/fastdfs # 第一个存储目录
    tracker_server=192.168.0.1:22122 # tracker服务器IP和端口
    tracker_server=192.168.0.2:22122 # tracker服务器IP和端口
    http.server_port=8888 # http访问文件的端口(默认8888,看情况修改,和nginx中保持一致)
    #编辑启动文件
    $ vim /usr/lib/systemd/system/fastdfs-storage.service
    
    [Unit]
    Description=The FastDFS File server
    After=network.target remote-fs.target nss-lookup.target
    
    [Service]
    Type=forking
    ExecStart=/usr/bin/fdfs_storaged /etc/fdfs/storage.conf start
    ExecStop=/usr/bin/fdfs_storaged /etc/fdfs/storage.conf stop
    ExecRestart=/usr/bin/fdfs_storaged /etc/fdfs/storage.conf restart
    
    [Install]
    WantedBy=multi-user.target
    
    $ systemctl daemon-reload
    $ systemctl enable fastdfs-storage.service
    $ systemctl start fastdfs-storage.service
    $ netstat -tulnp #查看服务是否启动,端口是否打开
    #查看集群状态
    $ fdfs_monitor /etc/fdfs/storage.conf list
    [2018-11-06 00:00:00] DEBUG - base_path=/data/fastdfs/storage, connect_timeout=30, network_timeout=60, tracker_server_count=2, anti_steal_token=0, anti_steal_secret_key length=0, use_connection_pool=0, g_connection_pool_max_idle_time=3600s, use_storage_id=0, storage server id count: 0

    复制代码

    Client配置

    复制代码
    $ vim /etc/fdfs/client.conf
    #需要修改的内容如下
    base_path=/data/fastdfs
    tracker_server=192.168.0.1:22122 # tracker服务器IP和端口

    #保存后测试,返回ID表示成功 如:group1/M00/00/00/xx.tar.gz
    $ fdfs_upload_file /etc/fdfs/client.conf testfile
    复制代码

    4、安装nginx和fastdfs-nginx-module

    下载nginx module

    $ wget https://github.com/happyfish100/fastdfs-nginx-module/archive/V1.20.tar.gz
    $ cp /opt/fastdfs/fastdfs-nginx-module-1.20/src/mod_fastdfs.conf /etc/fdfs

    安装nginx

    $ yum install nginx -y
    # 查看版本及编译参数
    $ nginx -v
    $ nginx -V

    添加nginx module

    复制代码
    wget http://nginx.org/download/nginx-1.12.2.tar.gz
    $ tar -zxvf nginx-1.12.2.tar.gz
    $ cd nginx-1.12.2/
    $ ./configure --prefix=/usr/share/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --http-client-body-temp-path=/var/lib/nginx/tmp/client_body --http-proxy-temp-path=/var/lib/nginx/tmp/proxy --http-fastcgi-temp-path=/var/lib/nginx/tmp/fastcgi --http-uwsgi-temp-path=/var/lib/nginx/tmp/uwsgi --http-scgi-temp-path=/var/lib/nginx/tmp/scgi --pid-path=/run/nginx.pid --lock-path=/run/lock/subsys/nginx --user=nginx --group=nginx --with-file-aio --with-ipv6 --with-http_auth_request_module --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module=dynamic --with-http_image_filter_module=dynamic --with-http_geoip_module=dynamic --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_degradation_module --with-http_slice_module --with-http_stub_status_module --with-http_perl_module=dynamic --with-mail=dynamic --with-mail_ssl_module --with-pcre --with-pcre-jit --with-stream=dynamic --with-stream_ssl_module --with-google_perftools_module --with-debug --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -mtune=generic' --with-ld-opt='-Wl,-z,relro -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -Wl,-E' --add-module=/opt/fastdfs/fastdfs-nginx-module-1.20/src/
    $ make
    $ cp objs/nginx /usr/sbin/nginx
    $ systemctl enable nginx
    $ systemctl restart nginx
    复制代码

    查看插件是否安装成功:

    $ nginx -V


    配置nginx访问

    复制代码
    $ vim /etc/fdfs/mod_fastdfs.conf
    #需要修改的内容如下
    tracker_server=192.168.0.1:22122 # tracker服务器IP和端口
    tracker_server=192.168.0.2:22122 # tracker服务器IP和端口
    url_have_group_name=true
    base_path=/data/fastdfs
    store_path0=/data/fastdfs
    #配置nginx.config
    $ vim /etc/nginx/nginx.conf
    #增加如下内容
    server {
            listen 8888; ## 该端口为storage.conf中的http.server_port相同
            server_name localhost;
            location ~/group[0-9]/ {
                root /data/fastdfs;
                ngx_fastdfs_module;
            }
            error_page 500 502 503 504 /50x.html;
            location = /50x.html {
                root html;
            }
        }
    #测试下载,用外部浏览器访问刚才已传过的文件,引用返回的ID
    http://192.168.0.10:8888/group1/M00/00/00/wKgAQ1pysxmAaqhAAA76tz-dVgg.tar.gz
    #弹出下载则目前nginx已经OK
    复制代码

    注:

    在nginx的构建中会遇到不少的报错,具体如下:

    • ./configure: error: the Google perftools module requires the Google perftools library. You can either do not enable the module or install the library.

              解决方法如下:

    $ yum install gperftools -y
    • /configure: error: the HTTP rewrite module requires the PCRE library.
      解决方法如下:
    $ yum -y install pcre pcre-devel
    • ./configure: error: the HTTP cache module requires md5 functions from OpenSSL library. You can either disable the module by using --without-http-cache option, or install the OpenSSL library into the system, or build the OpenSSL library statically from the source with nginx by using --with-http_ssl_module --with-openssl= options.
      解决方法如下:
    $ yum -y install openssl openssl-devel
    • ./configure: error: the HTTP gzip module requires the zlib library. You can either disable the module by using –without-http_gzip_module option, or install the zlib library into the system, or build the zlib library statically from the source with nginx by using –with-zlib= option.
      解决方法如下:
    $ yum install -y zlib-devel
    • ./configure: error: the HTTP XSLT module requires the libxml2/libxslt libraries. You can either do not enable the module or install the libraries.
      解决方法如下:
    $ yum -y install libxml2 libxml2-dev
    $ yum -y install libxslt-devel
    • ./configure: error: the HTTP image filter module requires the GD library. You can either do not enable the module or install the libraries.
      解决方法如下:
    $ yum -y install gd-devel
    • ./configure: error: perl module ExtUtils::Embed is required
      解决方法如下:
    $ yum -y install perl-devel perl-ExtUtils-Embed
    • ./configure: error: the GeoIP module requires the GeoIP library. You can either do not enable the module or install the library.
      解决方法如下:
    $ yum -y install GeoIP GeoIP-devel GeoIP-data
    • 在make过程中会出现一个报错:/usr/include/fastdfs/fdfs_define.h:15:27: fatal error: common_define.h: No such file or directory
      解决方法如下: 
    修改fastdfs-nginx-module-1.20/src/config文件,修改如下: 
    ngx_module_incs="/usr/include/fastdfs /usr/include/fastcommon/" 
    CORE_INCS="$CORE_INCS /usr/include/fastdfs /usr/include/fastcommon/" 
    然后重新./configure && make,就可以了

    5、配置文件访问的负载均衡和高可用

    在192.168.0.100和101上安装nginx、keepalived

    yum install -y nginx keepalived

    nginx的配置文件如下:

    复制代码
    upstream fdfs_group01 {
        server 192.168.0.10:8888 weight=1 max_fails=2 fail_timeout=30s;
        server 192.168.0.11:8888 weight=1 max_fails=2 fail_timeout=30s;
    }
    server {
        listen 80;
        server_name localhost;
        location /group01{
            proxy_next_upstream http_502 http_504 error timeout invalid_header;
            proxy_pass http://fdfs_group01;
            expires 30d;
        }
    }
    复制代码

    keepalived配置文件如下:

    复制代码
    global_defs {
       router_id LVS_DEVEL
    }
    
    vrrp_script chk_ngx {
        script "/etc/keepalived/check_nginx.sh"
        interval 2
        weight -5
        fall 3  
        rise 2
    }
    
    
    vrrp_instance VI_1 {
        interface eno16777984
        state MASTER
        priority 100
        virtual_router_id 11
        advert_int 1
        authentication {
            auth_type PASS
            auth_pass 1111
        }
    
        unicast_src_ip 192.168.0.100
    
        unicast_peer {
            192.168.0.101
        }
    
        virtual_ipaddress {
            192.168.0.200
        }
    
        track_script {
           chk_ngx
        }
        notify_master "/etc/keepalived/notify.sh master"  
        notify_backup "/etc/keepalived/notify.sh backup"  
        notify_fault "/etc/keepalived/notify.sh fault"
    }
    复制代码

    check_nginx.sh

    复制代码
    #!/bin/bash
    
    counter=$(ps -C nginx --no-heading|wc -l)
    if [ "${counter}" = "0" ]; then
        exit 1
    else
        exit 0
    fi
    复制代码

    OK,以上就是所有的安装步骤及相关配置。
